生物活性:Tamoxifen (ICI 47699) 是一種具有口服活性的選擇性雌激素受體調(diào)節(jié)劑 (SERM),可阻斷乳腺細(xì)胞中的雌激素作用,并可激活其他細(xì)胞(如骨骼)中的雌激素活性、肝臟和子宮細(xì)胞[1][2][3]。 Tamoxifen 是一種有效的 Hsp90 激活劑,可增強(qiáng) Hsp90 分子伴侶 ATP 酶活性。他莫昔芬還有效抑制傳染性 EBOV Zaire 和 Marburg (MARV),IC50 分別為 0.1 μM 和 1.8 μM,分別[5]。他莫昔芬激活自噬并誘導(dǎo)細(xì)胞凋亡[4]。他莫昔芬還能誘導(dǎo)CreER(T2)轉(zhuǎn)基因小鼠的基因敲除[6]。
體外:Tamoxifen (ICI 47699) 對 MCF-7 細(xì)胞 (EC50=1.41 μM) 表現(xiàn)出強(qiáng)烈的抑制作用,對 T47D 細(xì)胞 (EC50=2.5 μM) 的抑制作用較小,但不影響 MDA-MB-231 細(xì)胞[2]。
體內(nèi):向突變前小鼠注射他莫昔芬(75 mg/kg;在 6 周齡時注射 5 天)導(dǎo)致 floxed 外顯子切除,從而導(dǎo)致基因敲除[3] .
